  Purpose
Recent investigations from this group have identified that genetic variants of genes associated with monogenic forms of nephrolithiasis are expressed in idiopathic calcium oxalate kidney stone patients and could influence stone forming risk. Utilizing patient samples from the Mayo Clinic Florida Kidney Stone Registry, we will demonstrate that expression of these heterozygous mutations in idiopathic nephrolithiasis act as genetic modifiers of disease presentation increasing risk of kidney stone formation. Complimented by the analysis of environmental and lifestyle risk factors, these studies will define environmental and genetic susceptibility factors involved in kidney stone formation and reoccurrence.
